Also if this is the case then this router would be disappointing because my old 2013 64mb RAM router can power my external HDDs continuously with no hiccups.

I think it is more of the software because a reset would make it work again back to normal and even a thumb drive would show similar results. I do not have time to explore for now but will do over the weekends and explore with via ssh.

I’ll give feedback and update you all.

To everyone in this thread, thanks for all your help
